[bindings/java] Implement for jdbc's ResultSet

[seonWKim]

Purpose of this PR

Associate jdbc's ResultSet with the returned values from limbo's step function.

Changes

Rust

• Java_org_github_tursodatabase_core_LimboStatement_step now returns an object of java's LimboStepResult.java

Java

• Added LimboStepResult.java in order to distinguish the type of StepResult(which limbo returns) and to encapsulate the interpretation of limbo's StepResult
• Change JDBC4ResultSet inheriting LimboResultSet to composition. IMO when using inheritance, it's too burdensome to fit unmatching parts together.
• Enhance JDBC4Statement.java's execute method
  • By looking at the ResultSet created after executing the qury, it's now able to determine the (boolean) result.

Reference

• Add support for Java bindings  #615

limbo always returns StepResult::IO after returning the results of SELECT.

But in my local, it works as follows

Not sure why the test fails on workflow but works on my local machine. I'll further investigate and add the work in the following PRs(as this PR is getting big)

Maybe it's due to more restricted environment e.g. less number of threads(maybe one thread)
